A halin da yanzu, akwai karamin mutanen switchgear na tsohon karkashin tsari a Najeriya suna yi amfani da gasar SF₆ a ciki na zangon 0.5 - 0.6 MPa don inke gida. Amma, idan hawa na yau da dama ya shafi kimanin -32.5°C, za'a sanya gasar SF₆ ziyartar, wanda yake iya haifar da masana'antar gida da inganci na kayan aiki. Don in ba sa shiga matsalolin aiki na switchgear na tsohon karkashin tsari a wurare, ana amfani da tracing heaters don in ba sanya gasar SF₆. Amma, a lokacin aiki na tracing heaters, babu zan iya duba tasirin aikinta duk da ita, wanda yana iya haifar da aiki da kafuwarsa na kayan aiki.

Prinsipil na Aiki da Karamin Yanzu na Tracing Heater na Circuit Breakers na Tank na 500kV

Saboda circuit breakers na SF₆ suna da muhimmanci wajen kawo karfi ga masana'antar sanya a wurare, an fi saka tracing heater zuwa casing na circuit breaker don in ba sanya. Idan hawa na yau da dama ya shafi kimanin, yanayin temperature na tracing heater zai faru baki daya don in daɗe waɗannan gasar da ke ciki a circuit breaker. Idan hawa ya shafi kimanin -15°C, yanayin temperature zai faru baki daya, kuma bayan maƙashe suka kasa, zai taimaka da tracing heater ya yi waɗannan gasar. Idan tracing heater ya kashe ko yanayin temperature ba ta faru baki daidai, ba zan iya duba tun daga gaba, wanda yake iya haifar da aiki na duk circuit breaker.

Kudin Teknologi na Dubawa na Tracing Heater na Circuit Breakers na Tank na 500kV

Don in ci gaba irin aiki na tracing heater na system na dubawa, abubuwan da ke da muhimmanci shine maimakon current isolator na ke kusa da circuit na aiki na tracing heater. Ba a bace wannan device na yanayin start da kuma current isolator, inda za a iya duba indicator light na current. Tun daga rukunin indicator light, za a iya bayar da takardukan muhimmiyar staff. A lokacin aiki na kudin teknologi na tracing heater, babban rawa shine koyar da automatic switch don in kontrolle tracing heater, wanda yake iya yi amfani a kan al'amuran aiki na yanayin temperature.

A lokacin aiki na kudin teknologi na tracing heater mai sauƙi, kyautar gida shi ne 2400W, kuma current na aiki shi ne 10.09A. Tun daga dubawa na tracing heater, za a iya duba current na aiki a cikin circuit a baya-bayan. Current isolator na current ratio na 15/5A zai iya haɗa current na 10.09A zuwa current na 3.6A, wanda yake iya haifar da masu wasu masana'anta na circuit coil. Duk da haka, za a iya haɗa current range zuwa 2 - 9.9A, wanda yake iya taimaka da tsarin output current na current isolator, kuma yana tabbatar da cewa output action node drive yana daidaito da status na indicator light na circuit.

Tsarin Amfani na Device

Fara program min shortcut na "Linhai Tracing Heater Monitoring" a desktop na Win10 don in bude virtual machine kuma zama a WinXP. Sannan faɗa shortcut na "Tank-type Circuit Breaker Tracing Heater Monitoring" don in fara program kuma zama a tracing heater operation monitoring screen. Tun daga interface na parameter setting, za a iya set alarm threshold na current na tracing heater da alarm threshold na tracing heater ba a yi aiki idan hawa ya shafi kimanin.

An yi amfani da wannan don in bayyana hawa a box na centralized control kuma setting na starting temperature na heater da fan a cikin box. Faɗa record na aiki, zaɓi number na device da za a duba tun daga drop-down box, kuma duba record na aiki na device a lokacin daɗi. Bude record na fault don in duba record na fault na device a lokacin daɗi. System na dubawa na tracing heater zai iya yi amfani a kan computer-controlled testing na equipment, wanda yake iya ci gaba lokaci na testing da kuma taimaka da accuracy na testing.Configuration information zai iya kokarin a background da kuma saukar a database, kuma za a iya karɓar configuration information na musamman daga database. Don tracing heaters na musamman, allon configuration kawai zai zama da buƙata. Idan test items da parameters suka badala, zai iya yi amfani a kan corresponding information kawai, wanda yake iya ci gaba errors na repetitive operations. Tun daga identification na current signal na transmitter end a receiver end, za a iya haɗa transceiver line sequence zuwa automatic matching, wanda yake iya haifar da abin da ya shafi kimanin communication bayan bayan a kan manual sending da receiving ends.

Duk da haka, system na dubawa na tracing heater zai iya saukar results na testing da kuma judge corresponding results, kuma bayar da notification don optical fibers da ba su da yarda. Saboda haka, system na dubawa na tracing heater ya kamata a yi amfani a kan touch screen don in taimaka masu amfani. Don in tabbatar da cewa system na dubawa na tracing heater na IEE-Business ya ci gaba standards da specifications, an bayyana specific technical index requirements tun daga baya-bayan ɗaya: overall function, overall performance, laser source performance, laser detector performance, da kuma general requirements.

General requirements an samun baya-bayan ɗaya: working environment, appearance, safety, da kuma electromagnetic compatibility (EMC). Indicators da za su iya haifar da su an bayyana a matsayin key indicators. A cikin haka, saboda testing instrument, system na dubawa na tracing heater ya kamata a samun testers, test objects, da kuma environment. System na dubawa na tracing heater wanda ya kamata full-time human participation don in ci gaba testing tasks na unit under test an sanar da shi a matsayin manual tracing heater monitoring system. Hakanan, system na dubawa na tracing heater wanda ya kamata mallakar human participation kuma zai iya ci gaba majority of testing tasks automatically an sanar da shi a matsayin automatic testing system.

Abubuwan Da Ke Da Muhimmanci a Kudin Teknologi na Tracing Heater na Circuit Breakers na Tank na 500kV

Kudin teknologi na tracing heater ya taimaka masu aiki don in duba status na aiki na tracing heater a baya-bayan, wanda yake iya haifar da abin da ya shafi kimanin masu aiki. Duk da haka, dukkan system na dubawa na tracing heater yana da karfin anti-interference mai yawa. Tun daga output na moving da moving-break contacts, za a iya duba shi a main control room, wanda yake iya taimaka masu amfani. Dukkan system na dubawa yana da ƙarfin simple. Zai iya iya haɗa wire na heater a current isolator da kuma connection na indicator light a gaba.
